Web engineering

This volume contains the proceedings of the seventh International Conference on Web Engineering (ICWE2007), which was held in Como (Italy) in July 2007. The conference is the ? agship event of the community, promoting research and scienti? c progress in the Web engineering ? eld. The importance of the Web — and of its many related technologies— is widening the scope of the conference year after year, and is also leading to the cross-fertilization of several related disciplines (e. g., requirements engineering, testing and analysis, communication science, HCI, multimedia, and more). The conference brings together practiti- ers, scientists, and researchers committed to investigating and innovating the technologies, methodologies, tools, processes, and techniques used to construct, verify, and maintain Web-based applications and services. This year, the Call for Papers attracted a high number of submissions with a verygoodcoverageof allthe di? erentfacets of the Web engineeringdiscipline. A totalof172submissions(asforresearchpapers)allowedusto buildanattractive program of high technical and scienti? c quality. The 39 selected submissions comprise 26 full papers and 13 short papers (with an acceptance rate close to 23%); they cover the di? erent aspects highlighted in the Call for Papers and represent well the many Web engineering research groups active worldwide. The program spans from service-based systems to testing and analysis, from quality and metrics to models, and from semantic issues and Web 2.0 to application development techniques.
